    摘要: A network device for an intercom network for duplex audio communication between users of the intercom network has a housing and a communication module in or at the housing and that can establish a radio link for transmitting audio signals to and receiving audio signals from another user. The radio link is subject to the DECT protocol or another protocol, and the audio signals to the communication module is broken by reflection into a plurality of radio paths. Multipath interference is prevented or reduced by electronic elements including at least one equalizer for processing a plurality of audio signals received along the plurality of radio paths and performing a signal correction.

    摘要: A sealing unit used to block liquid comprises a sealing block, a receiving hole, a wire-through hole, and a sealing piece. The receiving hole penetrates the sealing block. The sealing piece is received in the receiving hole. A surface of the sealing block is in contact with the receiving hole. A material of the sealing piece is elastic material. The sealing piece is penetrated by the wire-through hole and forms an open penetrating structure. The present disclosure also provides a wireless intercom device using the sealing unit.
